Vibration detector and vibration detection method

Abstract

The invention discloses a vibration detector and a vibration detection method. The vibration detector comprises a vibration assembly and a control assembly connected with the vibration assembly. The vibration assembly comprises a shell, a vibration motor arranged in the shell and a vibration head connected with the shell, wherein the vibration motor is connected with the control assembly; the side, away from the shell, of the vibration head is of a curved-surface-shaped structure. The curved-surface-shaped structure comprises transition arc surfaces located at two ends of the vibration head, and concave arc surfaces which are in smooth connection with the transition arc surfaces at the two ends and are externally tangent to the transition arc surfaces. The vibration detector disclosed by the invention is designed according to a special anatomical structure of a neck tracheal ring, so the vibration detector is matched with the neck trachea and the anatomical structure, the contact surface is not too large or too small, other tissues of the neck are not stimulated, the test result is accurate, cough sensitivity objective evaluation indexes based on physical stimulation are obtained,adverse reactions are avoided, and the compliance degree of a subject is higher.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a vibration detector and a vibration detection method. Background technique [0002] Coughing is one of the most important respiratory defense reflexes in humans. Coughing is a double-edged sword. Under normal physiological conditions, coughing helps clear respiratory secretions and harmful factors. In a disease state, frequent and severe coughing can cause damage to the body and cause great distress to the patient. Increased cough sensitivity is a major clinical and pathophysiological feature of patients with cough. Therefore, the assessment of cough sensitivity is not only conducive to exploring the pathophysiological mechanism of cough and the development of new drugs, but also plays an important role in evaluating the patient's condition and curative effect. [0003] The airway afferent nerves that innervate the cough reflex include unmyelinated C fibers and myelinated Aδ ...

AI Technical Summary

Problems solved by technology

[0005] Based on this, the present invention aims to overcome the mismatch between the prior art physical stimulation instrument and the neck trachea and anatomical structure, which cannot well transmit vibration stimulation to the neck trachea, or may stimulate other tissues in the neck, resulting in inaccurate test results. Accurate defects, providing a vibration detector and vibration detection method
